3.3. 9-Stage Smart Charging Process

The charger employs an upgraded 9-stage charging process for safer and more efficient charging:

1. Battery Detection: Analyzes battery condition.
2. Battery Desulphation: Restores sulfated batteries.
3. Soft Start Charging: Gently initiates charging.
4. Bulk Charging: Provides maximum current until battery is 80% charged.
5. Absorption Charging: Reduces current as battery approaches full charge.
6. Battery Test: Checks battery health.
7. Recondition Charging: Further optimizes battery performance.
8. Float & Maintenance Charging: Maintains full charge without overcharging.
9. Monitoring Stage: Continuously monitors battery status.

4. Maintenance

The charger automatically enters trickle/float charging mode once the battery is fully charged. This feature maintains your batteries during extended periods of non-use, such as during summer, winter, or holidays, ensuring they remain in optimal condition. The high-efficiency pulse repair function automatically detects battery sulfation and acid stratification, working to restore lost battery performance for stronger engine starts and extended battery life. Note: This function cannot activate or charge totally dead batteries.

5. Troubleshooting and Protections

The NEXPEAK charger is equipped with multiple smart protections to ensure safe and reliable operation:

• Smart Control: Intelligent management of the charging process.
• Temperature Compensation: Adjusts charging parameters for hot and cold climates to prevent under-charging or overheating.
• Reverse Protection: Prevents damage from incorrect battery terminal connections.
• Cooling System: Ensures optimal operating temperature.
• Overcurrent Protection: Safeguards against excessive current flow.
• Fireproof Material: Constructed with fire-resistant materials for enhanced safety.
• Overcharge Protection: Prevents battery damage from prolonged charging.
• Short Circuit Protection: Protects against short circuits.

If the charger indicates a 'bad battery', it means the battery may be beyond repair or too deeply discharged to be safely charged by this unit. Always ensure proper connection and select the correct battery type for optimal performance and safety.
